The “mysql” service failed to start.

Suddenly MySQL died and cannot start again. All Drupal sites are down. I had this some 2 weeks ago and was unable to figure out how to fix, so had to restore the server (as per support). This is what I am getting when trying to start mysql:

Check directory permissions
/var/lib/mysql and the contents there in.
It should be owned by MySQL:MySQL.
Milind KoyandeCommented:
As arnold said check Permissions for the mysql directory. Also check what is in the /var/lib/mysql/ip-192-169-222-111.secureserver.net.err file.
